Personally, I tend to stick to the direct line and their siblings, but I also follow a line if I think it interesting. By doing this I found a few interesting people, including one that was lost on Titanic, who was a cousin of my gt gran, so, its worth following leads. I have to say though, just one line, my mum's paternal (Hulme) line, I've filled 5 lever arch files with BMD certs, news paper items, photos, post cards, Christmas cards from early 1900's and my very much treasured letter to my 2x gt grandad in 1888, along with any other info I find.
I should add, I've been looking at a tree belonging to someone else with 16,000 + names in it, I found glaring mistakes with their Hulme records, it seems my 2x granddad was born 2years after his father died, and many other mistakes, keep it simple but make sure its correct would be my advice.
Griff.
